JCZ-360超宽频带地震计研究与实验

Research and Experiments on JCZ-360 Ultra Broadband Seismometer

介绍了JCZ系列超宽频带地震计JCZ-360的研究进展、定型测试、台站实验观测等情况。结果显示,JCZ-360超宽频带地震计能有效抑制外界大气压力、外部磁场干扰及温度变化对仪器的影响,性能更稳定,在超低频端噪声水平更低。JCZ-360超宽带地震计不仅可以观测到全频段地震波,还可以记录到固体潮汐、地球自由振荡等信息,具备传统地震和地球物理场的综合观测能力。

This paper introduces the research progress,standardized test and experimental observation on seismic station of the JCZ series ultra broadband seismometer JCZ-360.The results show that the JCZ-360 ultra broadband seismometer can effectively suppress the influence of external atmospheric pressure,external magnetic field interference and temperature change on the instrument.Its performance is more stable and noise level is lower at the ultralow frequency terminal.The JCZ-360 ultra broadband seismometer can not only observe full-band seismic waves,but also record information such as solid tides and free oscillation of the Earth.It has the comprehensive observation ability of traditional seismic and traditional geophysical field.
